Re: [osg-users] outputsize of osgb and osgt
Hi Torben, The binary should be smaller than the ascii. Are you findings before or after compression? As for merging cluster support, I'd have to know a bit more about what form it would take. There are a number of different approach to doing clusters, each with their own strengths and weaknesses. I don't know much about how you are tackling it beyond that you're using the new serialization support. Robert.

hopefully the order of destruction will be sorted out too.
The modified src/osg/Referenced.cpp is now attached. The change to
ObserverNodePath.cpp can now be reverted as it's taught us all we can
get from this particular change.
With your own changes at your end it would be good to toggle it the
changes on/off so we can re-enable the error and test changes in the
OSG to see if we can fix it. I'm keen to see a fix on the OSG side if
we can as it may well be not just your app that is affected and could
well be a wider issue that lurks underneath apps unseen most of the
time and then pops up randomly.
Thanks for your help,

Re: [osg-users] outputsize of osgb and osgt
Hi Robert, my serialized sizes are: Ascii format: 137 byte binary format uncompressed 217 byte (!) binary format compressed 107 byte. 6 Month ago, I implemented 2 prototypes (TCP, UDP) . My result was, that TCP is not as fast as UDP, but it was the only possibilty to (nearly) sync the different channel's swap at final draw callback. On UDP I currently use broadcast, but thats not mandatory. Because of its unreliability, my UDP approach is fire and forget. So the slave tries to get as much as possible packets (to avoid framentation, the datacontainer must be smaller than the max payload of an UDP datagram) and uses the newest one for processing. My TCP approach was to send the frame information at the beginning to all slaves, then waits for all slave to report as ready, and if every client is ready, the sends the swap command to all clients. This solution was quite slow, so at the moment I focus an a UDP solution. I don't know which functionalities you would include in a cluster Node. Only transporting a transport container over network, or also complete frame sync? In my application I use to callbacks, eventdraw callback and finaldraw callback. At these two positions in the frame, the callbacks act depending of the role as master, slave or as standalone. They send information to slaves, receive information from master or do nothing. To make the cluster transparent to the scenegraph independent from the role, I implemented a dataIO interface which they query. Beyond this interface, there is the cluster driver (slave) or cluster driver + externalLink driver (master). The ladder connects the visual to its external control source, which can be a flighsimulator, a control program or anything else. My current transport content is: - viewmatrix - variables which are used of my objects updater classes - list of executer command, which can transport a command as enum and some parameter (e.g. to change weather at all clusternodes) This is my current approach. My project will be openscource in some days/weeks (depends on my time to set up my trac environment). Because you are under heavy load, maybe it is best If I continue my project, and when its published, you can take a look on it and we can discuss how man of the architecture could be abstracted, refactored to your wishes and included as cluster framework...

I'll be back at lunchtime, and if all looks well I'll go for making

Thanks for all the testing,

[osg-users] [osgPlugins] Synchronising DirectShow videos
Hi,
I'm currently using the DirectShow plugin to play two videos through
DirectShow, which works fine and as intended. I require both of these videos to
play completely in sync with one another, but as they play along they go out of
sync. I have tried comparing the current frame of each video and if different
seek them both to the same frame, but that, for obvious reasons, causes the
videos to stutter.
I did a bit of research into this on the web and came across a post detailing
several steps to synchronise two DirectShow graphs, the details are below:
* Pick one graph as the master.
* Make sure the master has a clock. This is normally done when going
active, but you can force it to happen earlier by calling SetDefaultSyncSource
on the graph.
* Query the graphs for IMediaFilter, get the clock from the master graph
using GetSyncSource and pass it to the other graphs using SetSyncSource.
* Pause all the graphs.
* Wait until GetState returns S_OK (the pause is complete).
* Get the time from the graph and add 10ms or so.
* Call IMediaFilter::Run on all graphs, passing this time (now + 10ms) as
the parameter.
Now to implement this I put an exported function into the DirectShow plugin
which lets me access the _renderer, using this I have implemented the above
steps as such:
DirectShowImageStream* s1 = dynamic_castDirectShowImageStream*(imagestream1);
DirectShowImageStream* s2 = dynamic_castDirectShowImageStream*(imagestream2);
IReferenceClock* pClock = 0;
s1-getRenderer()-_graphBuilder-SetDefaultSyncSource();
s1-getRenderer()-_mediaFilter-GetSyncSource( pClock );
s2-getRenderer()-_mediaFilter-SetSyncSource( pClock );
s1-getRenderer()-_mediaFilter-Pause();
s2-getRenderer()-_mediaFilter-Pause();
//while( (s1-getRenderer()-GetState(1000, State_Paused)
s2-getRenderer()-GetState(1000,State_Paused)) != S_OK )
//{
//}
Sleep(1000);
REFERENCE_TIME time = 0;
pClock-GetTime(time);
s1-getRenderer()-_mediaFilter-Run( time + 100 );
s2-getRenderer()-_mediaFilter-Run( time + 100 );
As you may notice the wait for the state is commented out as I cant seem to
find the correct enum for the second GetState parameter, I have add a
Sleep(1000) to try to compensate.
Using the above code both streams still play out of sync with one another, have
tested with the same video in both graphs and they do not align, I was hoping
maybe the author of the DirectShow plugin could advise me as to why this is the
case? I am new to DirectShow coding so any help anyone can give will be greatly
appreciated.
The video is encoded in HD using h264 and uses ffdshow codec when playing.
Thanks Nathan

Re: [osg-users] Problem displaying textures
Hi Julien, The application I am building models augmented reality for a see through display. Therefore the camera must integrate the position of the person, as well as camera (intrinsic) parameters that reflect the users eye+display combination. These I derive using 2D-3D correspondences based on the Single Point Active Alignment method developed at Technical University of Munich. Since the camera parameters already model a perspective position, the camera parameters are meant to be used with an orthogonal projection. Initially (before I apply parameters corresponding to the eye), the models appear fine: Pose matrix: based on the tracked location and orientation of the head The camera view matrix is updated as follows: Pose x Default transform The camera projection matrix is set to (not changed) a perspective projection (created using OSG) After the calibration procedure is performed/applied, the models are not textured well: Calibration matrix: models the position and orientation transform from the tracked point to the head, as well the eye View matrix: Pose x Calibration matrix Projection matrix: orthogonal projection The models are loaded using a Collada plugin (though there are also problems when I create the model myself following the osgteapot example). I dont change any other parameters except the camera parameter mentioned above, that is the model properties and statesets remain the same.

HI Nick,
I'm afraid I don't have ideas about the cause yet, the line of code
you quote where the crash occurs looks fine, the objects in play
should all still be valid. Does the error occur on standard OSG
examples? Does both the release and debug builds crash on exit?

Re: [osg-users] Please test svn/trunk for OpenThread/OpenSceneGraph
Hi Martin, Thanks for testing. The errors are down to two methods that I had their implementation from Registry into a dedicated companion class, alas I hadn't removed the declaration though so these methods were indeed the cause of missing symbols. I have now removed the offending methods and updated the wrappers. Could you do an svn update and let me know that the build now works fine, Thanks, Robert.

Hi Robert, I implemented my own ReadFile callback, working well. Would you (and osg) be interested in having it ? I can submitt in directly in osg src. I implemented if for WIN32 only, so someone should implement the other version... For the moment, it uses psapi.lib ... not very portable but maybe someone can help be making it portable and without other dependencies. Regards, Vincent.

So If I decrease this value, some PagedLod will be released ? It won't release any right away, but as the frames progress it'll work to get the max down to your specified target when it's possible. What difference with cameraLODScale ? The osg::Camera::setLODScale() just changes which children are selected in the view, it doesn't change the max number of PagedLOD target, but it will directly affect how many PagedLOD that will be active in any view. I just made a test increasing/decreasing this value and I saw the effect on PagedLod and memory. Yes, this is exactly how one would expect it to work.

Re: [osg-users] [osgPlugins] Synchronising DirectShow videos
HI Nathan, I now nothing about DirectShow so I can't comment on the API/impementation details of what you are trying to achieve. What I can say is that when I've done stereo movie rendering with the OSG we've rendered the two movies streams into a single movie then use texture coordinates to pick out the two halves. The osgstereoimage example shows how it's done for side by side Image, and the same code works for an ImageStream too.

[osg-users] [osgPPU] Ploblems with anaglyph stereo rendering
Dear all, I have been trying to apply osgPPU for stereo rendering and that appeared to work. However, when I took a closer look at the anaglyph rendering of the osgppu_dof example (run it with --stereo), I noticed that it does not work as expected (running the osgPPU pipeline on both views, then applying anaglyph), even though it kind of looks plausible. What happens instead is that the left render pass executes the pipeline on a red cow (osg uses colormasks for rendering the anaglyph). In the second pass, osg additionally renders the cyan parts into the same input texture and runs the right pipeline pass based on it. For the second frame, the input texture is still the previous anaglyph with updated red-channel. Both passes are using the correct depth buffer for their view. This problem is bugging me, as the same stereo pipeline works correctly with quad-buffered stereo. I think the fix would be to render both left and right views in full colour and then combine them in a shader to compute the final anaglyph image. This way it would also be possible to support other types of anaglyph, such as red-blue, green-magenta [1] or blue-amber [2], which may not be easily implemented using RGB colour masks. My question is: would this be a useful modification of osg? What do other people think? Thanks, Christian.

Re: [osg-users] [osgPlugins] Synchronising DirectShow videos
Hi Robert, My code is actually based on the stereo image example, but I am using two ImageStreams instead of the one. My application actually allows you load images or movies and renders them to two textures which you can then move around just like the example. It seems I may have to get the two movies into just one like you suggest, but like you I have no experience in DirectShow. Could you go into more details as to how you tackled it, and maybe I could adapt the same approach for my software. Once again thanks for the help.

It does sound kinda similar to the issue that Rafa had with destruction under OSX, but I've already checked in a fix for this which Rafa confirmed has worked. Is there any chance you haven't updated to the latest svn/trunk that includes the changes for fixing things under OSX? The issue under OSX was that the clean up of the app destructed the GlobalObserverMutex before the scene graph/viewer, and then when it came to clean up these structures the mutex pointer was invalid. If the fix for OSX doesn't work and still the static GlobalObserverMutex is getting destructed before the viewer then we could possible add a check into mutex locking code so that if the pointer has been reset to 0 then don't attempt to lock it. The GlobalObserMutex uses a custom smart pointer class to make sure the pointer is reset to 0 after deletion of the object so it should be possible to test against it at runtime as well as in the debugger.

Re: [osg-users] [osgPlugins] Synchronising DirectShow videos
Hi Nathan, I don't personally have a methodology for creating side by side video - I've just requested stereo movies for the modellers I've worked with, then just use movie tools on the Mac to re-render the movies into a single side by side movie. My guess is that you could probably code up a solution using ffmpeg without too much difficulty. Robert. On Fri, Feb 19, 2010 at 2:48 PM, Nathan Schofield john.smith.jsmit...@googlemail.com wrote: Hi Robert, My code is actually based on the stereo image example, but I am using two ImageStreams instead of the one. My application actually allows you load images or movies and renders them to two textures which you can then move around just like the example. It seems I may have to get the two movies into just one like you suggest, but like you I have no experience in DirectShow. Could you go into more details as to how you tackled it, and maybe I could adapt the same approach for my software. Once again thanks for the help.

Hi Nick,
I was just reviewing your the code you copied in your earlier message
(below) and spotted that the observer_ptr was access a local mutex
not the GlobalObserverMutex() as it should have been. I've just fixed
observer_ptr and am currently rebuilding. Could you try the
attached include/osg/observer_ptr.
I do testing at my end if everything goes smoothly will check the
change in. I really don't know if it would fix the problem you are
seeing, fingers crossed.

Did you use the second of observer_ptr header that I posted? As I

Since then my build has completed without problems.

Re: [osg-users] Please test svn/trunk for OpenThread/OpenSceneGraph
Hi Nick, I've just run the runexamples.bat and all the examples run cleanly so I've now checked in my change to observer_ptr. Robert. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Please test svn/trunk for OpenThread/OpenSceneGraph
Hi Robert,
with the latest files (including the observer_ptr you posted at 15:18)
everything is working fine for me now (Visual Studio 2008, Windows XP).
However, is observer_ptr's destructor thread safe? It looks like if the
target of _ptr were to be destroyed on another thread at the same time as
observer_ptr's destructor is running then there's nothing to stop the
observer_ptr calling removeObserver() on an invalid pointer.
How about:
~observer_ptr()
{
OpenThreads::ScopedLockOpenThreads::Mutex lock(*getObserverMutex());
if (_ptr) _ptr-removeObserver(this);
}

Re: [osg-users] Migrating from 2.8.2 to 2.9.6
Ok,
When loading cow.osg I experience the same problems described above. Works fine
when my app is compiled with osg 2.8.2, warning message and no visible geometry
when using v. 2.9.6.
When viewing an .osg version of my test plane, there don't seem to be any
special GL features being used. In fact, the files are nearly identical in each
case except for the placement of the camera node. In the file that works, the
camera is just under the root. In the other file, the camera is a level deeper
and there is a 'Use Camera' line at the root. Pertinent sections shown below:
Code:
}
}
}
CameraView {
UniqueID CameraView_3
DataVariance DYNAMIC
name osg_main_view
nodeMask 0x
cullingActive TRUE
referenceFrame RELATIVE
position 0 400 0
attitude -0.707179 -0 -0 0.707035
fieldOfView 60
fieldOfViewMode VERTICAL
focalLength 0
}
}
Code:
}
CameraView {
UniqueID CameraView_3
DataVariance DYNAMIC
name osg_main_view
nodeMask 0x
cullingActive TRUE
referenceFrame RELATIVE
position 0 400 0
attitude -0.707179 -0 -0 0.707035
fieldOfView 60
fieldOfViewMode VERTICAL
focalLength 0
}
}
}
Use CameraView_3
}
It seems strange that this would make any difference... Any ideas?
Thanks again,
Garrett

Curious. the objectDeleted(void*) method should be called on all the
observers of an object prior to the objects deletion - the delete is
called after the call to the observers.
You could try removing the if (ref_obj-referenceCouint()==0) part and
just leave the _ptr as they should be safe, the if statement is just
there for a belt and braces approach to the method and isn't critical.
While there is might fix the crash it wouldn't actually explain it.
Is there any chance that your app has unloaded a dll before all the
data associated with it has been safely destructed?
Another little check you could do is check the value of obj compared
to _ptr, in theory they should be the same but if they aren't then we
know that something else is going wrong along the way.

If you are not getting the errors with the 2.9.6 version of osgviewer, but only with your app, then clearly this is a problem with your app and will be impossible for anyone on this list to debug it telepathically.

Re: [osg-users] line wrap delimiters in osgText
Good point. Actually, I think the correct solution is more complicated than either of us is thinking. Right now the delimiters are allowed to be either the first or last character on a line, depending on what fits the best. This is clearly wrong since none of these characters should ever be the first on a line unless you're typing gibberish. I've never programmed a word processor, but I think the correct solution is this: 1. A new line should be started after a line's last hyphen or before its last whitespace. 2. If no suitable place to break a line is found, just start new line after the last character that fits on the line. 3. Whitespace should be removed from the beginning of the new line. Now I'll see if I can program this. -- Terry Welsh / mogumbo 'at' gmail.com www.reallyslick.com / www.mogumbo.com Message: 3 Date: Fri, 19 Feb 2010 07:18:42 + From: Robert Osfield robert.osfi...@gmail.com To: OpenSceneGraph Users osg-users@lists.openscenegraph.org Subject: Re: [osg-users] line wrap delimiters in osgText Message-ID: 7ffb8e9b1002182318j2c2760c9r334dd4b0f6008...@mail.gmail.com Content-Type: text/plain; charset=ISO-8859-1 Hi Terry, On Fri, Feb 19, 2010 at 12:48 AM, Terry Welsh mogu...@gmail.com wrote: In Text.cpp and Text3D.cpp, the current list of delimiters used to find the last character in a line is SPACE \n / , ; : .

Re: [osg-users] Creating a new AnimationPathManipulator.
Ok, i see what you are saying.. The reason I was changed that was because
referenceTime was getting reset back to realtime in the call to viewer.frame()
( more specifically, inside the Viewer::advance() function).
To avoid this, I don't call viewer.frame(), I now have to:
double simTime = 0.0;
while( !viewer.done() )
{
viewer.getFrameStamp()-setReferenceTime(simTime);
viewer.eventTraversal();
viewer.updateTraversal();
viewer.renderingTraversals();
simTime += 1.0;

Added a mutex to the copy constructor looks appropriate, but this isn't the issue we're up against. One thing that has occurred to be is that one possible reason for the divergence of the pointer values is multiple inheritance. Both Viewer and CompositeViewer use multiple inheritance though... One odd thing about CompositeViewer is that has virtual inherits from osg::Object, when ViewerBase already provides osg::Object. I don't know why it's like this, perhaps at one point in the past it was required then a refactor of VIewer/CompositeViewer didn't correctly pick up on this not being needed...

Re: [osg-users] [osgOcean] osgOcean with osgEarth
Okay, I'm seeing some decidedly weird results from mixing osgEarth and
osgOcean. I've attached a picture link, but here's the text description...
I've cut the code back to creating an osgEarth globe but I'm not putting any
map data into it. (If I do, I get the same results anyway.) This means that
without osgOcean attached to the graph, I get a gray sphere as expected, the
first image in the picture below.
If I turn on osgOcean, the sphere turns black but with a thin ocean-colored
band that varies in diameter, from the outer edge of the globe to about 10%
smaller (2nd image). The variation occurs only when I move the camera, and is
random in appearance. It does not move with the sphere as I rotate the view -
it is always centered on the middle of the sphere.
If I zoom in and tilt the camera so as to look along the surface of the globe,
the ocean-colored band gets bigger (while still hopping about in diameter) and
shows some of the expected reflective properties of the osgOcean surface (3rd
image). Up very close, it becomes bands of blue and blue-green that I can see
increase in complexity, adding more bands (3rd image).

Re: [osg-users] Please test svn/trunk for OpenThread/OpenSceneGraph
Hi Nick, I've been contemplating the crash you have and the mismatch of pointers, which is little doubt down to multiple inheritance causing difference between the osg::Referenced location and the pointer to the actual object (class T for the template). This difference means that casting the pointer the osg::Referenced to the class T will result in an error, and the crash you are seeing is almost certainly down to this. Give that the _ptr is of class T then it should be safe to use this to check for the referenceCount() so one fix would be just to use if (_ptr-referencedCount()==0). Given the role of objectDeleted() I don't think it really required to double check, the pointer really just can be reset. Could you do an svn update to the new mods that I've made to include/osg/observer_ptr and see if you're modified osgviewer and the standard osgcompositeviewer crash. I've attached the file.

Re: [osg-users] [ANN] OSG Virtual Planets, the core of gvSIG3D.
Hi Rafa Jordi, Rafa, something you said triggered an old memory of mine: I must run the vcvarsall.bat file to setup the correct environment for vs8 and for compiling from the command line. I only could guess that you opened the wrong Visual-Studio command line, so the environment is not correctly configured. So, I found vcvarsall.bat; I set up my cmd tool to run this batch file every time I start a cmd tool; and then I re-ran ant; EVERYTHING WORKED after that. :):) I have attached my installation guide for your review and use if you would like to have it. It is what I had to do to get osgvp to install and build under Windows XP 32-bit. As for using eclipse, I have not installed it yet for Windows. I would like to use NetBeans, though, for java development on windows and ubuntu. Have you ever used NetBeans to develop java applications that are based on osgvp? My next move is to start developing a simple java application that starts an osgvp window and displays a simple terrain file. Thank you for your support.

Re: [osg-users] Problem sharing statesets to more than one drawable
It doesn't sound reasonable that the Collada loader has created one drawable for all the geometry that shares a shader group across different high-level objects, unless it and you can be sure that you never need to manipulate the objects position, etc. seperately. On the other hand, it is entirely reasonable that the loader created one StateSet for that shader group, sharing the StateSet between all the drawables containing geometry that uses the shader group. If you're making changes to a StateSet that's used by one of these drawables, you'll see it in all the others that use it. If you're using getOrCreateStateSet to get a state set from one of these drawables and then bang on it, you're changing the shared state set. You're absolutely right. My problem is an assumption that I made after I initially experimented with binding a stateset to a drawable. At the time I just used getOrCreateStateSet after finding the drawable, then modified it. I mistakenly thought I was pointing to a single drawable, since it seemed to impact them all, but I realize now I was modifying the stateset that was already shared between the drawables. Based on this assumption, when I wrote my node visitor to find a drawable, I used the logic that I could stop traversing as soon as I found the drawable, since it referenced all of the faces associated with a shader group. This worked ok for a while, but when I changed the code to start sharing statesets and started using setStateSet, I was really only setting the SS for a single drawable when I assumed I was setting it for all. So I suppose my choices are to a) continue to just find the one drawable and modify the stateset that's already applied to it using getOrCreateStateSet(), or b) just search for all of the drawables with that name and use setStateSet() to apply the stateset we create. The problem with the first method is that it assumes whatever plugin we use to load the geometry is going to create a shared stateset for us automagically. We are fairly set on using collada, but I think I'm going to go with option B to be safe. In any case, I appreciate the response. It has helped clear up what was really happening.

Paul, finding which header is missing from the places where you get the errors would probably not be too hard. Robert, getting a header and trying a GL3 build would probably not be too hard.

[osg-users] newbie texture question
Hi, I am new to OSG and I am attempting to port some work that was done in directX over to OSG. I am using some of the basic geometric objects like osg::box and osg::sphere. I got those working like I wanted, but when I tried to add texture mapping to them the results are very different than what I got in DirectX. For example, by default in directX when I mapped a texture to a box then each face got a full copy of the texture. However, when I map the same texture to the box in osg I get some weird stretched lines over the faces. Do the standard geometric objects not have texture coordinates already defined, or am I doing something simple wrong? I have listed a code snippet below. I have also tried using all of the different texture modes, and none of them really worked. Do I have to set the texture coords up manually? Seems to defeat the purpose of having simple objects predefined if I have to do a bunch of manual texture corrdinate code for each one. I have attached an image example showing the difference between the directx and osg versions. Code: osg::ref_ptrosg::MatrixTransform gNode = new osg::MatrixTransform(osg::Matrix::translate(osg::Vec3(0, 0,0))); osg::ref_ptrosg::ShapeDrawable boxDrawable = new osg::ShapeDrawable(new osg::Box(osg::Vec3(0,0,0), 10, 10, 10)); osg::ref_ptrosg::Geode box = new osg::Geode; box-addDrawable(boxDrawable.get()); gNode-addChild(box.get()); root-addChild(gNode.get()); osg::ref_ptrosg::Image image = osgDB::readImageFile(gravel.bmp); osg::StateSet* state = box-getOrCreateStateSet(); state-setTextureAttributeAndModes(0, new osg::Texture2D(image.get())); Thank you!

For example: 1) If I have a switch node and want to change its state in the update or event sequence (i.e during runtime), does the data variance need to be DYNAMIC? If I look at the _switch node in osgViewer::StatsHandler, it is not set to DYNAMIC although it is changed dynamically during runtime. 2) If I add a child node to a simple Group node (again during runtime), does the Group node need to be DYNAMIC? 3) If I have a my target has a MatrixTranform node and I decide to update its matrix, does it need to be DYNAMIC?

Guy Volckaert wrote: Hi, I'm little confused about when it's appropriate or even necessary to call setDataVariance(DYNAMIC) - assuming we are not running in SingleThreaded mode. You should read through the archives, as this has been discussed quite a bit. In summary, DYNAMIC keeps things thread-safe in osgViewer multithreaded modes, and keeps the Optimizer from optimizing away your nodes. 1) If I have a switch node and want to change its state in the update or event sequence (i.e during runtime), does the data variance need to be DYNAMIC? No. Switch nodes aren't part of the render graph, they're processed during cull. This means you can alter the Switch during event/update and rest assured that no draw thread is trying to access your Switch. 2) If I add a child node to a simple Group node (again during runtime), does the Group node need to be DYNAMIC? Same as for Switch. 3) If I have a my target has a MatrixTranform node and I decide to update its matrix, does it need to be DYNAMIC? I don't think so, because if I remember correctly the CullVisitor stores only the accumulated transformation in the render graph, which means that after cull is complete, draw never references the MatrixTransform and you're free to change it. You should look at the CullVisitor code to be sure. In all three of these cases, you might want set the DataVariance to DYNAMIC anyway, or at least add a comment saying it's not necessary and why. This might make it easier for future developers maintaining your code. -Paul ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] svn trunk build broke
Hi Paul, Paul, finding which header is missing from the places where you get the errors would probably not be too hard. I often do provide fixes, but I'm under the gun to get demos out the door in a few days. And Robert's under the gun (perhaps his own gun) to get a dev release out the door in a few days too. So suggesting he set up something new at this point in time was the same as him suggesting you fix the code yourself :-) Also, the general rule for most software development projects is: you break it, you fix it. I understand where you're coming from, but the fact is that when there are multiple code paths (and even more so when there are code paths determined at configure-time with #defines) it becomes hard and time-consuming to test each and every combination. I think it's reasonable for Robert to rely on the community for some of this, especially for configurations he doesn't use day to day. Just look at how many times I've submitted Windows build fixes in the past 3 years - I cut my teeth in OSG submissions on that stuff! For now, I see GL3 as the same thing - OSG's primary developer doesn't use the configuration (he could, I agree, but that's not the point), so it's up to others to test that it builds and runs for now. Although I also agree with your point that getting an automated build going for each configuration would be easy too, but crunch time was probably not the right time to suggest this... In effect, both of you were saying I can't fix this, I'm too busy with other things, you should fix it. And one of you had actually broken it, but the other had the errors right there in front of them. So you both could have fixed it. That's all I wanted to emphasize. Robert, keep in mind that words account for only a small percentage of communication, which makes it easy to read attitude into someone's text-only post, where none actually exists. That's so true. Most flame wars start because one poster reads more into the words than what was actually there, and then things escalate.
